We're dividing 843749 by 90 
Let's see how many times 90 fits into 843749.

Advancing to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 90

Going ahead to step 2:
84 divided by 90 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 90

On to step 3:
The number 90 fits into 843 9 times, leaving a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 810 from 843 leaves us with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 90

Moving on to step 4:
When dividing 337 by 90, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
The remainder is 67 after subtracting 270 from 337.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 90

Advancing to step 5:
90 goes into 674 7 times with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 937.0
If we take 630 away from 674, we end up with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 90

Let's proceed to step 6:
90 goes into 449 4 times with a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 9374.0
Subtracting 360 from 449 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 7:
90 can be fit into 890 9 times, resulting in a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 9374.9
Subtracting 810 from 890 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
800 divided by 90 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 9374.98
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 9374.988
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 9374.988 with a remaining 0.008.
